Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water outlet valve and a water circuit system of a wall-mounted boiler. Background Art

[0002] The water circuit system of a wall-mounted boiler is a water heater powered by natural gas. It has a powerful central heating function for families, can meet the heating needs of multiple rooms, and can provide domestic water for use in places such as family bathing and kitchens.

[0003] The water circuit system of a wall-mounted boiler in the related art usually includes a combustion chamber, a heat exchange structure, a water inlet valve, and a water outlet valve. The combustion chamber is usually installed on the indoor wall. The water inlet valve can supply water to the combustion chamber. The heat exchange structure includes a heat exchange channel and a water supply channel that cooperate for heat exchange. The water outlet valve includes a valve body and a switching device. The valve body is provided with a hot water inlet, a heating water outlet interface, a bathroom water outlet interface, a heat exchange inlet interface, and a heat exchange outlet interface. The hot water inlet is connected to the outlet of the combustion chamber. The heat exchange inlet interface is connected to the inlet of the heat exchange channel. The heat exchange outlet interface is connected to the outlet of the water supply channel. The bathroom water outlet interface is connected to the heat exchange outlet interface. After the water in the water supply channel exchanges heat with the heat exchange channel, it can flow to the bathroom water outlet interface through the heat exchange outlet interface to provide bathroom hot water for users. The hot water inlet is switched through the switching device to selectively connect to the heating water outlet interface or the heat exchange inlet interface.

[0004] However, the water outlet valve in the prior art often has the following problems: 1) The three-way valve cavity is coaxially arranged with the heating channel, and the axial direction of the three-way valve cavity extends in the up-down direction during installation, resulting in a relatively large size of the entire water outlet valve in the height direction, and further causing a relatively high installation height of the entire water circuit system of the wall-mounted boiler, which cannot meet the market demand for miniaturization of the water circuit system of the wall-mounted boiler; 2) The valve body is provided with a bypass valve part for replenishing water to the heat exchange structure to avoid damage to the heat exchange structure caused by dry burning due to water shortage. However, the bypass valve part is often installed behind the valve body. When it is necessary to repair the bypass flow channel in the bypass valve part, it is extremely inconvenient to remove the entire water outlet valve from the heat exchange structure.

[0053] Figure 1 The schematic diagram of the water circuit structure of the wall-mounted boiler water circuit system provided in this embodiment is shown. Figure 2 The schematic diagram of the water outlet valve 100 provided in this embodiment is shown from one perspective. Figure 3 The schematic diagram of the water outlet valve 100 provided in this embodiment is shown from another perspective. As Figures 1 - 3 shown, this embodiment provides a wall-mounted boiler water circuit system, which includes a combustion chamber 200, a heat exchange structure 300, a water inlet valve 400 and a water outlet valve 100. The combustion chamber 200 can heat the water therein; the heat exchange structure 300 includes a heat exchange channel 310 and a water supply channel 320 in thermal cooperation; the water inlet valve 400 can supply water to the combustion chamber 200 and the water supply channel 320; the water outlet valve 100 includes a valve body 1, and the valve body 1 is provided with a hot water inlet 1111, a first heat exchange water inlet flow channel 131, a first heat exchange water outlet flow channel 141, a heating channel 121 and a bathroom channel 142; the hot water inlet 1111 is connected to the hot water outlet 201 of the combustion chamber 200 through a connecting pipeline 600, and the hot water inlet 1111 can be selectively connected to the heating channel 121 or the first heat exchange water inlet flow channel 131; the first heat exchange water inlet flow channel 131 is connected to the inlet of the heat exchange channel 310, the outlet of the heat exchange channel 310 is connected to the second heat exchange water outlet flow channel 402 of the water inlet valve 400, the inlet of the water supply channel 320 is connected to the second heat exchange water inlet flow channel 401 of the water inlet valve 400, and the outlet of the water supply channel 320 is connected to the first heat exchange water outlet flow channel 141.

[0054] In use, when the hot water inlet 1111 is in communication with the heating channel 121, the hot water heated in the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipe 600, the hot water inlet 1111, and the heating channel 121 in sequence and then flow into the heating system 500 to provide heating requirements for users. The water that has exchanged heat with the outside in the heating system 500 can then flow into the combustion chamber 200 through the water inlet valve 400 to be reheated, thus forming a heating water circulation loop; when the hot water inlet 1111 is in communication with the first heat exchange water inlet channel 131, the hot water heated in the combustion chamber 200 can flow through the hot water outlet 201, the connecting pipe 600, the hot water inlet 1111, and the first heat exchange water inlet channel 131 in sequence and then flow into the heat exchange channel 310 of the heat exchange structure 300. After exchanging heat with the water in the water supply channel 320, it flows into the combustion chamber 200 through the water inlet valve 400 to be reheated, thus forming a heat exchange circulation loop; the water in the external water source can flow into the water supply channel 320 of the heat exchange structure 300 through the water inlet valve 400. After exchanging heat with the water in the heat exchange channel 310, it then flows through the first heat exchange water outlet channel 141 and the bathroom channel 142 in sequence and into the bathroom system to provide domestic water for users.

[0055] It should be noted that the heating system 500 specifically refers to terminal heat dissipation components such as radiators, floor heating pipes, or fan coil units. The water heated in the combustion chamber 200 can be pumped to the above-mentioned terminal heat dissipation components through the water outlet valve 100, and the heat is dissipated into the indoor air through heat dissipation, thereby increasing the indoor environmental temperature to meet the heating requirements of users. The bathroom system specifically refers to water-using devices for users to take showers, wash, etc. Therefore, both the heating system 500 and the bathroom system are relatively mature technologies in this field, and the specific structures of the heating system 500 and the bathroom system will not be elaborated in this embodiment.

[0056] This embodiment does not limit the material of the connecting pipe 600, and it can be made of copper pipes, corrugated pipes, stainless steel pipes, plastic pipes, etc.

[0057] It should also be noted that both the combustion chamber 200 and the water inlet valve 400 are relatively mature technologies in this field, and the specific structures of the combustion chamber 200 and the water inlet valve 400 will not be elaborated in this embodiment.

[0058] Optionally, the valve body 1 further includes a bypass valve portion 15, and the bypass valve portion 15 is used to supply water to the heat exchange structure 300 when the hot water inlet 1111 is in communication with the heating channel 121, so as to prevent the heat exchange structure 300 from being damaged due to dry burning caused by water shortage. However, in the prior art, the bypass valve portion is often installed behind the valve body. When it is necessary to repair the bypass flow channel in the bypass valve portion, the entire water outlet valve needs to be removed from the heat exchange structure, which is extremely inconvenient. To solve this problem, this embodiment also provides a water outlet valve 100, which can facilitate the operator to repair the bypass valve portion 15.

[0059] Figure 4 FIG. 1 is a schematic structural diagram of the water outlet valve 100 provided in this embodiment from another viewing angle. Figure 5 Shows Figure 4 Schematic diagram of the cross-sectional structure at AA. Figures 4 - 5 Combined with Figure 3 As shown, the outlet valve 100 provided in this embodiment includes a valve body 1, the valve body 1 includes a valve body 10, a first valve part 13 and a bypass valve part 15, the valve body 10 includes a three-way valve part 11 and an extended valve part 12 connected to the three-way valve part 11, the three-way valve part 11 is formed with a first cavity 1102, a main valve cavity 1101 and a second cavity 1103 sequentially arranged along a first direction, and the main valve cavity 1101 can selectively communicate with the first cavity 1102 or the second cavity 1103, and the extended valve part 12 is provided with a first cavity 1102 extending along a second direction. The heating channel 121 is connected to the first cavity 1102; the first valve part 13 is connected to the valve body 10, and the first valve part 13 is provided with a first heat exchange water inlet channel 131 connected to the second cavity 1103; the bypass valve part 15 is connected to the side of the three-way valve part 11 away from the first valve part 13, and the bypass valve part 15 is provided with a bypass channel 151, which can selectively connect the first cavity 1102 and the second cavity 1103; wherein the first direction is arranged at an angle to the second direction.

[0060] Compared with the prior art solution of coaxially arranging the three-way valve portion 11 and the extended valve portion 12, the outlet valve 100 provided in this embodiment can greatly reduce the size of the valve body 1 in the first direction by arranging the valve body 10 to be the three-way valve portion 11 and the extended valve portion 12 connected at an angle, and make full use of the size of the valve body 1 in the second direction, thereby achieving the effect of reducing the height of the valve body 1, and then reducing the installation height of the entire wall-mounted boiler water system to meet the miniaturization requirements of the wall-mounted boiler water system; by arranging the bypass valve portion 15, when the main valve chamber 1101 is connected to the first chamber 1102, When the heat exchange structure 300 is dry-burned due to lack of water, the water in the first chamber 1102 can flow through the bypass channel 151 and then through the second chamber 1103 and the first heat exchange water inlet channel 131 to the heat exchange channel 310 of the heat exchange structure 300, so as to avoid damage to the heat exchange structure 300 due to lack of water, thereby ensuring the safety of the heat exchange structure 300. By connecting the bypass valve part 15 to the side of the three-way valve part 11 away from the first valve part 13, the operator can inspect and maintain the valve body 10 from the side thereof without removing the entire water outlet valve 100, thereby improving the convenience of the operator's operation.

[0061] For ease of description, Figure 2 and Figure 3As shown, the height direction of the water outlet valve 100 after actual installation is defined as the up-down direction. Among them, the side of the water outlet valve 100 close to the combustion chamber 200 is defined as up, the side of the water outlet valve 100 away from the combustion chamber 200 is defined as down, the side of the water outlet valve 100 close to the heat exchange structure 300 is defined as back, and the side of the water outlet valve 100 away from the heat exchange structure 300 is defined as front; when the user stands facing the front of the water outlet valve 100, the side of the water outlet valve 100 facing the user's right hand is defined as right, and the side of the water outlet valve 100 facing the user's left hand is defined as left. In addition, the height direction of the valve body 1 refers to the up-down direction, the width direction of the valve body 1 refers to the left-right direction, and the thickness direction of the valve body 1 refers to the front-back direction. That is to say, in this embodiment, the bypass valve portion 15 is connected to the left side of the valve main body 10.

[0062] It should be noted that in this embodiment, the first direction specifically refers to the front-back direction, and the second direction specifically refers to the up-down direction. That is to say, the three-way valve portion 11 extends along the front-back direction, the extended valve portion 12 extends along the up-down direction, and the three-way valve portion 11 and the extended valve portion 12 are arranged perpendicular to each other. Of course, in other embodiments, the three-way valve portion 11 and the extended valve portion 12 can also be arranged at other angles, and the above effects can also be achieved.

[0063] Continue as Figure 3 and Figure 5 As shown, a bypass port 152 communicating with the bypass flow channel 151 is provided on the bypass valve portion 15. The bypass port 152 is detachably blocked by a bypass plug 153, and the bypass plug 153 faces the front side of the valve body 1. This design enables that when the operator faces the water circuit system of this wall-mounted boiler, the operator is directly opposite to the bypass plug 153, and the bypass plug 153 can be conveniently opened to repair the bypass flow channel 151 in the bypass valve portion 15, which is convenient and fast.

[0064] Optionally, a check valve 1511 is provided in the bypass flow channel 151 to only allow the water in the heating channel 121 to flow to the second chamber 1103 and prevent the water in the second chamber 1103 from flowing back. Among them, the check valve 1511 is a valve structure commonly used in the art, and the specific structure and working principle of the check valve 1511 will not be elaborated in this embodiment.

[0065] In this embodiment, the axis of the bypass valve portion 15 is inclined relative to the axis of the three-way valve portion 11. Specifically, the bypass valve portion 15 gradually inclines outward along the direction from back to front, so that the bypass plug 153 is as far away from the three-way valve portion 11 as possible, thereby preventing interference between the operator and the three-way valve portion 11 when the operator needs to open the bypass plug 153.

[0066] As Figure 2 and Figure 3As shown, the valve body 1 further includes a second valve portion 14. The second valve portion 14 is connected to the valve main body 10, and the first valve portion 13 and the second valve portion 14 are arranged at intervals in the vertical direction. Both the first heat exchange water outlet channel 141 and the sanitary channel 142 are provided in the second valve portion 14. It should be noted that, in this embodiment, the three-way valve portion 11 is arranged in the front-rear direction, the extended valve portion 12 is connected to the lower part of the three-way valve portion 11, and the first valve portion 13 and the second valve portion 14 are respectively connected to the right side of the three-way valve portion 11 and the right side of the extended valve portion 12, so that the entire valve body 1 is generally square in layout, making full use of the space of the valve body 1 in the width direction and the thickness direction, greatly reducing the installation height of the entire water circuit system of the wall-mounted boiler, and optimizing the space layout of the entire system.

[0067] Figure 6 Fig. shows a schematic structural view of the water outlet valve 100 provided in this embodiment from another perspective. Figure 7 Shows Figure 6 The cross-sectional structural view at B-B. Figure 8 Fig. shows a schematic structural view of the switching mechanism 3 and the separating component 112 provided in this embodiment. Figure 9 Fig. shows a cross-sectional structural view of the switching mechanism 3 and the separating component 112 provided in this embodiment. As Figures 6 - 9 shown, the water outlet valve 100 further includes a switching mechanism 3. The switching mechanism 3 is movably arranged in the three-way valve portion 11 to selectively open the passage between the main valve cavity 1101 and the first cavity 1102 or the passage between the main valve cavity 1101 and the second cavity 1103. When the switching mechanism 3 opens the passage between the main valve cavity 1101 and the first cavity 1102, the hot water in the combustion chamber 200 can circulate in the heating water circulation loop; when the switching mechanism 3 opens the passage between the main valve cavity 1101 and the second cavity 1103, the hot water in the combustion chamber 200 can circulate in the heat exchange circulation loop, that is, the switching mechanism 3 realizes the switching between the heating water circulation loop and the heat exchange circulation loop to selectively provide domestic water for users or meet the heating needs of users.

[0068] Specifically, the three-way valve portion 11 includes a body 111 and a partition assembly 112 disposed in the valve cavity of the body 111. The partition assembly 112 includes a first partition sleeve 1121 and a second partition sleeve 1122. The first partition sleeve 1121 and the second partition sleeve 1122 are spaced apart along the axial direction of the valve cavity of the body 111 and are both sealingly fitted with the cavity wall of the valve cavity of the body 111, thereby partitioning the valve cavity of the body 111 to form a main valve cavity 1101, a first cavity 1102, and a second cavity 1103. The first partition sleeve 1121 is located between the main valve cavity 1101 and the first cavity 1102, and the second partition sleeve 1122 is located between the main valve cavity 1101 and the second cavity 1103. The switching mechanism 3 includes a valve stem 31, a first seal seat 32, and a second seal seat 33. The first seal seat 32 and the second seal seat 33 are arranged at intervals along the axial direction of the valve stem 31 and are both connected to the valve stem 31. The valve stem 31 can move along the axial direction of the three-way valve portion 11, thereby driving the first seal seat 32 and the second seal seat 33 to move, so as to selectively block the first partition sleeve 1121 by the first seal seat 32 or block the second partition sleeve 1122 by the second seal seat 33. When the first seal seat 32 blocks the first partition sleeve 1121, the second seal seat 33 is spaced apart from the second partition sleeve 1122. At this time, the main valve cavity 1101 is communicated with the second cavity 1103. When the second seal seat 33 blocks the second partition sleeve 1122 and the first seal seat 32 is spaced apart from the first partition sleeve 1121, the main valve cavity 1101 is communicated with the first cavity 1102, thereby realizing three-way switching.

[0069] Optionally, the water outlet valve 100 further includes a driving mechanism (not shown in the figure). The output end of the driving mechanism is connected to the valve stem 31 to drive the valve stem 31 to move along the axial direction of the three-way valve portion 11. In this embodiment, the driving mechanism is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 3, the driving mechanism can also be a stepping motor or other driving devices.

[0070] It is worth noting that by arranging the three-way valve portion 11 in the front-rear direction, the driving mechanism can also be installed on the front side of the valve body 1 (the driving mechanism in the prior art is usually installed between the valve body and the combustion chamber), so as to avoid the spaced area between the valve body 1 and the combustion chamber 200, make full use of the space of the valve body 1 in the thickness direction, further shorten the distance between the valve body 1 and the combustion chamber 200, and reduce the height of the entire water circuit system of the wall-mounted boiler.

[0071] Such as Figure 3 and Figure 7As shown, the first chamber 1102 is connected to the heating passage 121 through the heating communication flow passage 1001, and the axis of the heating communication flow passage 1001 is inclined relative to the axis of the three-way valve portion 11. In the prior art, the first chamber 1102 and the heating passage 121 are coaxially arranged and extend in the up and down direction. When the switching mechanism 3 opens the passage between the main valve chamber 1101 and the first chamber 1102, the first sealing seat 32 is equivalent to blocking the passage between the first chamber 1102 and the heating passage 121, and the water in the main valve chamber 1101 will flow between the periphery of the first sealing seat 32 and the chamber wall of the first chamber 1102, resulting in a large water resistance. In this embodiment, by providing the inclined heating communication flow passage 1001, an opening can be exactly formed at the interval in the direction of the axis of the three-way valve portion 11 downward between the first sealing seat 32 and the first partition sleeve 1121, and the water in the main valve chamber 1101 can flow out from this opening under the action of its own gravity, thereby reducing the water resistance, increasing the water flow rate to a certain extent, and also playing a role in reducing the head damage of the circulating water pump, prolonging the service life of the circulating water pump, and reducing the user's usage cost.

[0072] As Figure 5 and Figure 6 shown, the second chamber 1103 is connected to the first heat exchange water inlet passage 131 through the heat exchange communication flow passage 1002, and the axis of the heat exchange communication flow passage 1002 is inclined relative to the valve body 10. Compared with the straight passage in the prior art, in this embodiment, by providing the inclined heat exchange communication flow passage 1002, it is equivalent to increasing the cross-sectional area of the inlet of the heat exchange communication flow passage 1002, thereby reducing the water resistance of the water flowing from the second chamber 1103 to the first heat exchange water inlet passage 131.

[0073] It should be noted that the heating communication flow passage 1001 and the heat exchange communication flow passage 1002 that are inclined relative to the axis of the three-way valve portion 11 achieve the direct connection between the corresponding flow passages. This design is convenient for processing, can reduce the use of sealing plugs, and can also reduce the potential risk points of leakage.

[0074] Figure 10 shows a schematic structural diagram of the water circuit system of the wall-mounted boiler provided in this embodiment. Figure 11 shows a schematic structural diagram of the water circuit system of the wall-mounted boiler provided by the prior art. As Figure 10 and in combination with Figure 2 , Figure 3 shown, the hot water inlet 1111 is opened on the three-way valve portion 11 and is connected to the main valve chamber 1101 to receive the hot water flowing out from the hot water outlet 201 of the combustion chamber 200. In this embodiment, the hot water inlet 1111 on the three-way valve portion 11 is arranged facing the hot water outlet 201 of the combustion chamber 200, and the hot water inlet 1111 and the hot water outlet 201 are directly connected through the connecting pipe 600. Compared with Figure 11For the solution shown in which the hot water inlet 1111 is arranged on the side of the valve body 1, with the above arrangement, after the connecting pipeline 600 is led out from the hot water outlet 201, it can be directly pulled down to the hot water inlet 1111, thereby shortening the distance between the hot water inlet 1111 and the hot water outlet 201, reducing the length and material consumption of the connecting pipeline 600, and thus can reduce the material cost to a certain extent; in addition, the above arrangement also enables the connecting pipeline 600 to be processed into a straight pipe structure, and the connection between the hot water inlet 1111 and the hot water outlet 201 can be achieved without too many bending parts, thereby avoiding the phenomenon of large water resistance caused by too many bending parts on the connecting pipeline 600.

[0075] In this embodiment, the hot water inlet 1111 is coaxially arranged with the heating channel 121, and the first chamber 1102 and the second chamber 1103 are respectively located on both sides of the axis of the hot water inlet 1111, so as to facilitate the processing of the valve body 1. Of course, in other embodiments, the axis of the hot water inlet 1111 and the axis of the heating channel 121 can also be arranged to be parallel but not coaxial, and the above effects can also be achieved.

[0076] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
